Overview
The BT131-800D,412 is a bidirectional triac manufactured by WeEn Semiconductors. It features an RMS on-state current of 1 A and a non-repetitive peak on-state current of 13.8 A. The device has a rated repetitive peak off-state voltage (VDRM) of 800 V and an off-state leakage current of 100 uA at VDRM. Key electrical parameters include an on-state voltage of 1.2 V, a maximum holding current of 5 mA, a gate trigger voltage of 700 mV, and a gate trigger current of 3.8 mA. It operates within a temperature range of -40 C to +125 C.
Feature Summary
- Bidirectional switching capability for AC control applications
- High thermal stability with operation up to +125 C
- Robust surge handling with high non-repetitive peak current
Applications
- Lighting dimmers
- Motor speed controls
- Heating element regulation
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS and REACH compliance requirements as stated in the datasheet. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component based on its 800 V blocking voltage and 1 A continuous current rating. Consider the TO-92-3 package for through-hole mounting constraints. Evaluate the gate trigger characteristics against the driving circuit capabilities to ensure reliable turn-on under varying load conditions.
Part Context
This part belongs to the BT131 series of bidirectional triacs from WeEn Semiconductors. The series is designed for general-purpose AC power switching. The '800' designation indicates the voltage class, while the 'D' suffix typically denotes the specific package variant within the product line.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative components by matching key electrical parameters such as VDRM, IT(RMS), and package dimensions.
